What Causes Power Steering Failure?
2 Answers
Power steering failure can be caused by a leaking power steering booster, insufficient power steering fluid, or a damaged power steering pump. For hydraulic power steering systems, it is necessary to check whether the pump belt is too loose or has come off. For electronic power steering systems, it is also important to inspect the motor or wiring for any issues. Below is an extended explanation: 1. Introduction to Power Steering: Power steering assists the driver in adjusting the car's direction, reducing the effort required to turn the steering wheel. It also plays a role in the safety and fuel efficiency of the vehicle. Currently, the power steering systems installed in cars can be broadly categorized into three types: mechanical hydraulic power steering systems, electro-hydraulic power steering systems, and electric power steering systems. 2. Introduction to Hydraulic Power Steering Systems: Mechanical hydraulic power steering systems generally consist of components such as a hydraulic pump, oil pipes, a pressure and flow control valve body, a V-type drive belt, and a fluid reservoir. This system operates continuously, whether the car is turning or not, and requires the hydraulic pump to deliver more power at lower speeds during sharp turns to provide greater assistance.
Steering assist failure is a common issue in daily driving. I often encounter car owners seeking advice. The cause may be a faulty power steering pump or insufficient pressure due to hydraulic fluid leakage. In electric systems, interruptions are prone to occur due to motor damage or sensor failure, while issues like short circuits or controller bugs can also cause problems. If you feel the steering wheel becoming heavy while driving, pull over immediately, turn on the hazard lights, and avoid forcing the car to move to prevent loss of control. Start with simple checks: see if the fuse is blown or if there's any hydraulic fluid leakage. Regular maintenance should include checking steering pressure and replacing aged fluids or belts. I recommend car owners learn basic self-inspection to save on repair costs and ensure driving safety. Addressing potential issues early is always better than dealing with accidents later.
